Abstract

A Inconel 718 is one of representative Ni-base superalloys. However, it is not easy to produce the complicate shaped parts at low cost due to their poor workability. In this study, Metal Injection Molding (MIM) process, one of near net-shape forming of powders, has been applied for fabricating the Inconel 718 compacts using different type of powders; gas and water atomized powders. By optimizing the MIM process, their obtained relative density was near full density (98~99%) and the tensile property of as-sintered compacts was the strength of 1000MPa and the elongation of around 10%, which are similar to that of wrought materials. High temperature and fatigue properties of heat treated MIM compacts will be discussed in detail at the conference.
